Equivalency and Prerequisites

College Course Equivalent

A college precalculus course or a college algebra with trigonometry course.
  

Recommended Prerequisites

You should have successfully completed introductory algebra and geometry courses. In particular, you should be able to demonstrate proficiency with linear functions, polynomial addition and multiplication, factoring quadratic trinomials, using the quadratic formula, solving right triangle problems involving trigonometry, solving linear and quadratic equations and inequalities, algebraic manipulation of linear equations and expressions, and solving systems of equations in two and three variables. You should also be familiar with piecewise-defined functions, exponential functions and rules for exponents, radicals (e.g., square roots, cube roots), and complex numbers.
